Abstract (en)

[origin: DE10112674C1] The device has a master cylinder connected to a slave cylinder with a membrane (12) fixed at its edge to a casing (10), which together define a chamber (16). The chamber is connected to the master and slave cylinders, so that the membrane is acted on by hydraulic fluid between the two cylinders. The membrane is pressed by a spring element (22) against the direction of hydraulic action against a support surface (24) on the chamber side, at least in a rest state. An Independent claim is included for a hydraulic force transmission system.
